Abstract

Patente de Invenção: <B>"PROCESSO PARA ACABAMENTO DE PINOS EM TRIPéS"<D>. Para complementar e aperfeiçoar um processo para o acabamento de pinos em ferramentas como tripés, cruzamentos de articulação e peças internas de articulação, onde as ferramentas são primeiramente fabricadas por moldagem extrudada e os pinos, em estado acabado, exibem reentrâncias de forma anelar em suas extremidades livres e na passagem do pino para o corpo médio, de tal forma que o acabamento dos pinos nestas ferramentas seja facilitado em relação às reentrâncias, também na passagem dos pinos para o corpo médio e a segurança da ligação entre ferramenta e elemento correspondente, criada por meio dos anéis de segurança permaneça intocada, onde no mesmo passo de trabalho ou em passo de trabalho diferente também seja possível um acabamento terminado da superfície de pino, de forma simples, as reentrâncias nos pinos são introduzidas por moldagem a frio por meio de rolamentos, após a fabricação da ferramenta fabricada através de moldagem extrudada e/ou as superfícies dos pinos são ajustadas por meio de rolamentos.Invention Patent: <B> "PROCESS FOR FINISHING PINS IN TRIPODS" <D>. To complement and perfect a process for finishing pins on tools such as tripods, articulation crossings and internal articulation parts, where the tools are first manufactured by extruded molding and the pins, in finished condition, exhibit annular recesses at their ends free and in the passage of the pin to the medium body, in such a way that the finishing of the pins in these tools is facilitated in relation to the recesses, also in the passage of the pins to the medium body and the security of the connection between tool and corresponding element, created by the safety rings remain untouched, where in the same work step or in a different work step a finished finish of the pin surface is also possible, in a simple way, the recesses in the pins are introduced by cold molding by means of bearings, after the manufacture of the tool manufactured through extruded molding and / or the sup pin surfaces are adjusted using bearings.
